Two eggs any style -- generalizing egg-drop experiments [PDF]
arXiv, 2022 The egg-drop experiment introduced by Konhauser, Velleman, and Wagon, later generalized by Boardman, is further generalized to two additional types. The three separate types of egg-drop experiment under consideration are examined in the context of binary decision trees.

Encapsulation and Self-Superparasitism of Pseudapanteles dignus (Muesebeck) (Hymenoptera: Braconidae), a Parasitoid of Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae). [PDF]
PLoS ONE, 2016 Endoparasitoids can be killed by host encapsulation, a cellular-mediated host immunological response against parasitism that involves hemocytes aggregation.

Unapparent trees: escaping enemies in time by being discreet, unpredictable and inaccessible
Oikos, EarlyView.For half a century, biologists considered trees as particularly apparent to their enemies. But why then do some trees escape herbivorous enemies by bursting buds either too early or too late, leading to phenological mismatch? We hypothesize that such mismatches occur on trees that are unapparent in time – those that burst buds ‘discreetly' (slowly) and

The evolution of gregariousness in parasitoid wasps [PDF]
, 1998 Data are assembled on the clutch-size strategies adopted by extant species of parasitoid wasp. These data are used to reconstruct the history of clutch-size evolution in the group using a series of plausible evolutionary assumptions.

Oikos, EarlyView.Information processing by herbivorous insects can impair the accuracy of decision‐making during host‐plant selection. Consequently, insects with a narrower diet breadth are expected to be more accurate decision‐makers, as they cope with a smaller set of relevant stimuli.

Temperature-dependent development of Habrobracon hebetor (Hym.: Braconidae) reared on larvae of Galleria mellonella (Lep.: Pyralidae) [PDF]
نامه انجمن حشرهشناسی ایران, 2008 The development times and the survival rates of different stages of Habrobracon hebetor Say reared on the last instar larvae of Galleria mellonella (L.) were compared at ten different constant temperatures (16 - 38 ºC).

European Journal of Entomology, 2009 Gronotoma micromorpha is a solitary egg-pupal and larval-pupal parasitoid. In a previous study, the developmental time of this parasitoid decreased with the age of its leaf miner host, Liriomyza trifolii, being significantly longer when the host was 0 ...
